Embodiment Construction

[0024] according to figure 1 The braking device 1 of the embodiment comprises an electromagnetic elevator brake 3 and a device 2 for driving the electromagnetic elevator brake 3 . In this respect, the electromagnetic elevator brake 3 does not have to be part of the device 2 . In particular, the device 2 can also be produced and sold independently of the electromagnetic elevator brake 3 . Furthermore, embodiments of the device 2 are possible which enable the device 2 to be adapted to electromagnetic elevator brakes 3 of different designs.

[0025] Such as Figure 4 As shown schematically in , the braking device 1 is used for an elevator installation 70 by way of example. The elevator installation 70 comprises a car 71 which is connected to a counterweight 72 via a supporting device 73 , for example a supporting belt. To this end, the support device 73 is suspended, for example, by support rollers 77 . The or each support means 73 is driven by a drive pulley 75 whereby the ...

Abstract

The application discloses a device (2) for driving an electromagnetic elevator brake (3), in particular for an elevator system, comprising a control system (30) and at least two outputs (24, 25), the at least two The outputs (24, 25) are connected to the coil (5) of the electromagnetic elevator brake (3). A switchable dissipation device (20) is also provided, the switchable dissipation device (20) being connected to the two outputs (24, 25). In the fast drive mode of operation, the control unit (30) switches the switchable dissipation device (20) so that the magnetic energy stored in the coil (5) is quickly dissipated. Therefore, rapid driving of the elevator brake (3) can be performed. Also disclosed are a brake device (1) comprising said device (2), an elevator system and a method for driving an electromagnetic elevator brake (3).

Description

technical field [0001] The invention relates to a method for operating an electromagnetic elevator brake, a device for operating an electromagnetic elevator brake, a braking device and an elevator installation with a corresponding controller. Such braking devices are preferably used when the elevator installation is stopped at a stop or when the elevator installation needs to be braked quickly in an emergency situation. Background technique [0002] An emergency control device for a car is known from GB 2 153 465 A. In known control devices, the braking force of the elevator braking device can be controlled stepwise or continuously depending on the load of the car. This control device has the disadvantage that the elevator brake can only respond after a certain time. During this time, for example, the car can be accelerated. The travel of the car and the braking distance covered in response to the elevator brakes will then increase. [0003] Known solutions are disclosed...
